α-Catenin (α-cat) is an actin-binding protein required for cell-cell cohesion. Although this adhesive function for α-cat is well appreciated, cells contain a substantial amount of nonjunctional α-cat that may be used for other functions. We show that α-cat is a nuclear protein that can interact with β-catenin (β-cat) and T-cell factor (TCF) and that the nuclear accumulation of α-cat depends on ...

The levels of cathepsins in malignant and surrounding nonmalignant lung tissue were determined in 17 non-small cell lung cancer specimens. Cathepsin (Cat) D activity was assayed using hemoglobin, whereas Cat B and Cat L activities were assayed using fluorimetric substrates, benzoylcarbonyl-Ala-Arg-Arg-7-amino-4-methylcoumarine and benzoylcarbonyl-Phe-Arg-7-amino-4-methylcoumarine, respectively....

In this paper, a proposed encryption scheme based on Henon chaotic system (PESH) is presented in order to meet the requirements of secure image transfer. Scheme based on Henon chaotic system by Chen Wei-bin et al., will be designated here as (SHCH). SHCH and a proposed encryption scheme (PESH) are applied for encrypting by changing the values of the image pixels. Combination of shuffling the po...

The bidirectional gated recurrent unit (BiGRU) method based on dissolved gas analysis (DGA) has been studied in the field of power transformer fault diagnosis. However, there are still some shortcomings such as fuzzy boundaries DGA data, and BiGRU parameters difficult to determine. Therefore, this paper proposes a diagnosis landmark isometric mapping (L-Isomap) Improved Sand Cat Swarm Optimizat...

BACKGROUND Cat exposure during childhood has been shown to increase the risk of developing cat sensitization, while the effect of cat exposure in adulthood has not yet been established. OBJECTIVE To evaluate new-onset sensitization to cat in adulthood in relation to changes in cat keeping. METHODS A total of 6292 European Community Respiratory Health Survey I (ECRHS I) participants aged 20 ...

The ability of domestic cat or leopard cat spermatozoa to penetrate zonae pellucidae (ZP) of salt-stored, domestic cat oocytes was examined as an assay for sperm capacitation. Ovarian oocytes were recovered after ovariectomy and matured in vitro for 18-36 h. Following removal of cumulus cells, the oocytes were used fresh, or stored (4°C, 0.5-24 weeks) in a HEPES-buffered hypertonic salt solutio...

background: cells have complex network of antioxidant enzymes that protect cells from induced damages by reactive oxygen species (ros). catalase and superoxide dismutase are known for their role as primary protection against oxidative stress. oxidative damage is an important risk factor in age-related macular degeneration disease (amd). for the first time in this study the impact of genetic pol...
